Effects of the Earthquake of March 27, 1964, at Seward, Alaska.
Alaska 1964 In this prezi, we will be talking about the Great Alaska Earthquake, also know as the Good Friday Earthquake and the Alaska Tsunami in 1964. The Great Alaska Earthquake, the most powerful megathrust earthquake (earthquake that occurs in the subduction zone) ever.
On March 27, Good Friday of 1964 at 5:36 PM violent shaking erupted without warning across South Central Alaska. The most powerful earthquake ever in North America Raged for nearly five minutes. The earthquake and ensuing tsunami took the lives of 118 unfortunate souls; thousands were left in the snow without shelter, food, and water.

The Earthquake of 1964 claimed the lives of approximately 131 people in Alaska as well as 16 deaths between Oregon and California. For an earthquake this size, the death toll was quite small, due to the low population, the time of day in which it occurred and the fact it was a holiday.
Many of the fatalities in the 1964 earthquake in Alaska were caused by tsunamis at Valdez, Alaska; near the epicenter in Kodiak, Alaska; and as far away as Hawaii and in Crescent City, California, where 11 people were killed. In 1998, a huge tsunami killed 10,000 in Papua New Guinea.
The understanding gained from the 1964 Great Alaska Earthquake provided the geological framework for assessing the earthquake and tsunami hazards at all convergent margins around the world. For example, the tsunamis produced by the 1964 Great Alaska Earthquake was one of the first events to demonstrate to scientists that an earthquake.
Case Study 2: 1964 Port Alberni Tsunami On the afternoon of Good Friday, March 27, 1964, the strongest earthquake recorded in North America, and the second strongest ever recorded, occurred in Alaska. The Great Alaskan Earthquake was a 9.2 magnitude subduction zone (megathrust) earthquake located at a depth of approximately 25 kilometres.
